| Abstract: | Since no one has done this before,we use Gamma-Gamma scintillation distribution to model the atmospheric turbulence channel and analyze the error performance of the atmospheric laser communication system with digital subcarrier PSK intensity modulation.The results indicate that subcarrier PSK intensity modulation system has preferable performance and the potential to realize the reliable communication. |

| Keywords: | atmospheric laser communication error performance subcarrier PSK modulation Gamma-Gamma distribution |
